Presentation on theme: "By Danny and Dane. Europa is the sixth moon of Jupiter’s 67 moons. It is frozen over by ice. There is a possibly of water underneath its surface."— Presentation transcript:
Scientists belive that Europa has an outter layer of water that is 100km thick Probably sea of salty liquid This layer is predicted to be made of both water and ice It is the sixth largest moon and the fifteenth largest object in the universe It also holds a metalic iron core Parts of Europa’s crust is said to have shifted by about 80 degrees which would not be possible without the pressence of water
One of the smoothest objects in the solar system The surface of Europa is smooth because it is very young and active The radiation is very high which would cause harm to human beings who endure it The icy crust on Europa cause it to be shiny and reflective The surface is around twenty to 180 million years old
The dark crisscrossing lines on the surface of Europa are its most remarkable feature The larger lines on the surface are about 20 miles across! The reason for the cracks are said to be because the crust opens up to expose the expanding warmer layers beneath Jupiter’s pull and the fact that Europa’s crust rotates faster than its core could explain the cracks also
There are also features called lenticulae, they are dark and raised circular landforms The domes that are formed seem to be pushed up from under the crust Reasoning behind this is that the warmer ice pushes up through the colder ice against the surface
Europa’s atmosphere is said to be made up of mostly oxygen molecules The surface pressure of Europa is 10^-12 times of Earths But it is not that type of oxygen found on earth, the oxygen on Europa is starts with water then is split by radiation forming hydrogen and oxygen molecules The oxygen stays in the atmosphere while the hydrogen molecules are too light and escapes the atmosphere
